ROTARY ENGINE.

Specification of -Letters Patent.

Patented .rane s, 1909.

To all whom it may concern.'

Be it known that I, TrioMAs JoReENsEN,

citizen of the United States, residing at Mar- -tinez, inv the county of Contra Costa and State of California., have invented new and useful Improvements in Rotary Engines; of which the following is a specification.

My invention relates to motors, and particularly that class of motors designated rotary engines". i f

It is desirable to devis-e an engine of this character which will be simple in `operation and construction which will be'valveless and which, when desired,.lmay berun upon `the compound system.

Among the other objects of my invention may be mentioned the provision of a structure with a minimum number of independent and movable parts, and also thepro'vision of a motor in which a minimum amount of packing to prevent leakage or loss of pressure is required.

My invention consists of the parts, thereonstruction and the combination of parts, or

/ their e uivalents, as set forth in the specification an accompanying drawingshin which Figure -l is a view taken on hne x-x of Fig. 3, looking in the direction of the arrow. Fig. 2 is a horizontal section on the line y-fy of Fig. 3 looking down. Fig. 3 is a vertical transverse section through the. motor, thc rotor being in elevation. Fig. 4 is a detail transverse section through the rotor. Fig. 5 is a detail showing the abutment member. Fig. 6 is a detail view in perspective showing a portion of the rotor memberwith its tie 18.

The mode of construction and o eration, as shown in the accompanying di'awings, illustrates one form in which my invention may be embodied, and comprises a separable casino 2 in which is formed a suitable steam cham er 3, and Within which rotates a suitable piston or rotor 4, which as here shown comprises two disk-shaped members 5 and 6, one of which, 6, is splined upon a shaft 7, to which the other member 5 of the rotor may be rigidly secured.

I have provided smallspringdike members 23 which 'are secured to the peripheral sur# faces of the members 5 and 6, and are adapted to serve as packing members against the inner surface of the chamber 3,' and prevent the escape of steam around the edge of the rotor 4.

The shaftv 7 has suitable journals in the casing 2, and projects from the side thereof in such a manner as to afford means from which ower may be transmitted in any desirabie manner.

The disks 5 and 6 are provided with plane surfaces adapted toybe set face to face, and

as being in the shape of truncated cones 7 The rotor 4 is designed to have rotation in the journals of the casing 2 upon an approximately horizontal axis, and the rotor revolving in a lvertical plane at right angles thereto.

The steam chamber 3 isy cylindrical in form, and its axis is at a slight inclination to the axis of the rotor 4, as shown at af-aFig. 3.

The inclination of the Walls of the steam chamberv 3 coincides exactly with the anguin such a manner that as the rotor revolves it has a constant line contact, as shown at b-c, with the Walls of the chamber 3.

The peculiar angular disposition of the chamber 3, with relation to theV rotor 4, provides suitable steam chambers upon each side of the rotor 4, and as shown at Sis an inlet port communicating with one side of the chamber 3, and upon the same side as the port 8 of the casing, is an outlet port 9 for the escape of steam.

The inlet and outlet of the steam ma be controlled by any suitable syst'em of va ves, such as shown at 10, whereby the steam may bereversed in its direction, so that the direc tion of rotation of the motor may be reversed; but it will be seen that these valves form no operative combination withthe motor proper, and only afford a means of reversing the inflowing steam.. y

The rotor 4, which as'before mentioned, is composed of two individual members 5 and 6, and these members are adapted to be thrust apart by suitable springs 11, located at suitable points between faces of the members 5 and 6.

.The function of the springs 11 is to thrust the. members 5 and 6 outwardly, and into intimate contact with the walls of the casing at the points b-c. Obviously, during the contact at their conical surfaces 7 with the walls, at the points b.-c in the steam cham- A means comprising a loosely mounted floating vane or abutment member l2, is prosuitable slot formed transversely across Ythe the outer sides of the disks 5 and 6 are shown the facing sur-l continuous rotation of the rotor, the disk' members 5 and 6fwil1 always be in intimate larity of the cone surfaces 7 of the rotor 4,

vided, and is adapted to oscillate or slide in a Y con-tour.

rotor 4, in such amanner that as the rotor is revolved, the abutment 12 will be carried around thereby, and will continuously oscillate bach and forth approximately upon a pivot 13 in the shaft 7, between the wallsb-c of the steam cylinder 3.

As shown in Fig. 3, the steam Cylinder at the left hand side of the casing, is of smaller diameter than that portion in the right hand side of the casing, and its peripheral Walls are shown as being concentric with lthe pivotal point 13, about which the abutment 12 os cillates. Thus, it will be apparent that as the rotor is revolved, the angularity of the walls of the chamber 3, will cause the abutmentl 1.2 to slide transversely through its bearing in the rotor 4, at each rotation of the rotor. For instance, in Fig. 2, the rotor is* shown as standing in a position midway between the inlet port 8, and the exhaust port 9, .and when it is in this position, the pressure of the steam is effective against the upper portion of the vane- 12, as shown in Fig. 3, to rotate the piston 4, 'and by reason of the contact at point b with the cone 7', the steam cannot ass in this direction, and is directed upwardly between the surfaces of the chamber 3 and the cone 7', and abuts against the surface of the vane 12, and is thereby prevented frorn escaping directly to the exhaust port 9. The continued rotation of the rotor 4 carries the blade or vane 12 around until it reaches the point b of the casing, when it' will then. be flush with the su'rface of the cone 7 on one side, and is projected through the side of the cooperative piston member 6 in the lower portion of the other side of the/piston chamber`3, as clearly shown.

The steam ports on the right hand side of the casing as shown in Fig. 3, are disposed above the horizontal axis of the rotor, while those on the left hand side of the casing are disposed below the shaft. i

The peripheral surfaces of the members 5 and 6 of the rotor 4, and of the piston or vane 12, are spherical Vin form, and designed to con form closely 'to the inner peripheral surface of the chamber 3, which is also spherical in.

In this way the vane 12 may reciprocate freely back ahd forth through the rotor 4 as it is carried around.

The vane 12 is always disposed betwee the inlet passage 8 andthedischarge passage 9 in such a manner that there is never a direct communication between the two, and further the conical walls 7 of the rbtor are always in close contact at the points b so that the steam cannotescape past this oint and be lost, but must always trave up and around, and impinge against the vane 12 before it can reach the exhaust port 9 on the opposite side, at the point '0, a similar seal is a ways maintained. As the vane 12 travels in its orbit constantly in contact with the walls of the cylinder 3, it will be oscillated4 back and forth in such a manner as to ahr-rnately be interposed inthe upp'mportionof the steam'cylinder 3 at each revolution, and simultaneously into the lower portion of the steam cylinder 3 on the riffht hand side of the machine, and when it is desired to make the engine of a compound ty e, it is only necessary to connect the ex raust ports ofthe smaller portion of the steam chamber 3 with the inlet port of the larger side of the chamber 3 by suitable connections shown at 19.

In this manner advantage is taken ofthe expansibility of the steam.

I have shown at 14, an annular vpar-,hingring adapted to be thrust against theplane surface of the rotor member G ,b vsuitable springs 15 to prevent loss of pressure at this portion of the steam chamber; and I have also provided suitable paclringf hars 2() mounted in slots formed inthe edgesA of the vane 12, which bars 20 are actuated upon by small s rings 21. of any suitable character. inserte y in the body of the vane 12, and forces the bar 20 into steam tight engagement with the walls of the steam chamber 3. The ends of the abutment 12 are shown as curvilinear in shape so as to conform with the inner periphery of the chamber 3, and are of such length as to pro erly seat in the separate portions of the cham er 3, and shown as having projections 22 for4 this purpose. This abutment vane 1-2 is shown as composed of two removable members secured upon the central stem 16 which is adapted to ass through a suitable slot 17 formed in the shaft 7, and through whichit may have free oscillation;

The rotor members 5 and 6 are united to each other by a tie 18 at the point where the slot is formed in the rotor through Ywhich the vane 12 is reciprocable or oscillatable.

Having thus described my invention, what I claim and desire to secure by Letters Patent 1s.-
